Abstract:
:The preparation of a novel peptide/dendrimer hybrid is reported in which an elastin-like oligopeptide is successfully assembled onto a poly(amidoamine) dendrimer surface (G4-ELP), and its unique thermo-responsive behavior is discussed. As a result, the G4-ELP is found to exhibit LCST behavior in the pH range 3-10 including physiological temperature range under neutral-pH conditions. Moreover, cooperative interplay between the folding state of the ELP shell and the ionization state of the dendrimer core enables the G4-ELP to control its LCST widely by pH variation. This achievement provides a new insight for the design of dual-responsive materials with a potential in biological applications.
